PTP Aluminum Foil (Pharmaceutical Thermoformable Packaging Aluminum Foil) is a core sealing material for pharmaceutical aluminum-plastic blister (PTP) packaging. Composed of "pure aluminum foil substrate + pharmaceutical-grade coating", it adheres tightly to blister substrates (such as PVC, PVC/PVDC rigid sheets) through a heat-sealing process, strictly complying with pharmaceutical packaging standards like YBB and ISO 15378.
Its core advantages lie in "high barrier property + safe adaptability": the pure aluminum foil substrate can effectively block oxygen, water vapor, light and odors, preventing drug oxidation, moisture absorption and photosensitive degradation (e.g., antibiotics, vitamins); the pharmaceutical-grade coating (such as acrylic resin) on the surface ensures no migration of harmful components during heat-sealing, guaranteeing drug safety.
In addition, PTP aluminum foil can accurately adapt to high-speed blister packaging equipment, support printing of drug batch numbers, expiration dates and other information, and has good tearability for easy access by patients, making it a key pharmaceutical packaging material that balances protection, compliance and practicality.
